Find the center and radius of the circle given by this equation: x^2 - 10x + y^2 + 6y - 30 = 0

Answers

Answer:

center=(5,-3)

radius = 2 unit

Step-by-step explanation:

         Center with the equation x² - 10x + y² + 6y - 30 = 0 is (5, -3) and the radius is 8 units.

Circle with the given center and radius: Equation of a circle with the center (h, k) and radius 'r' is given by,

         (x - h)² + (y - k)² = r²

         Here, Center of the circle → (h, k)

                    Radius of the circle → r units

Given equation of the circle in the question is,

x² - 10x + y² + 6y - 30 = 0

Convert this equation to the standard equation of the circle.

x² - 2(5x) + y² + 2(3y) - 30 = 0

[x² - 2(5y) + 5²] - 5² + [y² + 2(3y) + 3²] - 3² = 30

(x - 5)² - 25 + (y + 3)² - 9 = 30

(x- 5)² + (y + 3)² = 64

(x- 5)² + (y + 3)² = 8²

     Therefore, center of the circle is (5, -3) and radius of the circle is 8 units.

Which of the following best shows two elements combining to form a compound!? Explain...

What is molecular structure?

The term "molecular structure" refers to the structure of a molecule that merely consists of the arrangement of its atoms.

A chemical compound is a material made of several similar molecules that are linked together by chemical bonds and are made up of atoms from various elements.

Chemical compounds cannot be created when two atoms of the same element are bound together since this would need the presence of two distinct elements.

In diagram C it is obtained that atoms are combined to form the compound.

The finest example of two components combining to make a compound is in Option C.

Hence, option C is correct.

What is the solution of the equation 8(g - 18) =160

Answers

Answer:

g = 38

Step-by-step explanation:

8(g - 18) = 160

8g - 144 = 160

g = (160 + 144) / 8

g = 38

Answer:

g = 38

Step-by-step explanation:

8(g - 18) = 160

8g - 144 = 160

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J

Answers

Answer:

The correct option is;

C. 4800 J

Step-by-step explanation:

The given parameters are;

The mass of the skier = 40 kg

The height of the slope = 12 meter

The acceleration due to gravity, g = 10 m/s²

The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h

Substituting the values, gives

The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J

The potential energy, PE = 4800 J

Area= Sq.feet
Perimeter= Feet

Answers

Answer:Area = 4700 feet squared

Perimeter= 288 feet

Step-by-step explanation:

Length = 94 feet

Width = 50 feet

Area = Length × Width

= 94 feet × 50 feet

= 4700 feet squared

Perimeter = 2(Length + Width)

= 2(94 feet + 50 feet)

= 2(144 feet)

As they prepared for their trip, they had many questions. How would they travel there? What time of year was best for traveling? What would they bring?For answers, they turned to immigrant guidebooks. They also read letters from friends or family who had already emigrated. In the end, though, settlers had to rely on their own judgment about what to bring. Poor packing decisions could lead to serious problems in the first year, especially for farmers in remote areas. An overpacked wagon was costly and difficult to transport. Forgetting to pack an important item could also be disastrous.Make a list.Imagine you are part of an immigrant family moving to Minnesota in 1858.Read through the list of possible items to pack in your wagon. Note how many points each item is worth. A higher number means an item is difficult to move or very valuable.On a separate sheet of paper, list the items you choose to bring and describe why. Remember the following when packing for your move:1. Your total points may not be more than 60.2. You must give at least one reason for every item you bring.3. You will be farming, so you will not be able to visit the town frequently. Your first trip to town will happen one month after you arrive.4. You may bring more than one of each item, but you must add up all the points (for example, 1 pillow = 1 point; 2 pillows = 2 points).
